Dunham had set apart working hours, and he seemed to labor with double vigor then because of the other task he had set himself. When at last he finished the legal business he had come for, and might go home, he lingered yet a day, and then another, devoting himself with almost feverish activity to the search for his unknown friend.

It was the evening of the third day after his law work was finished that with a sad heart he went toward the hotel where he had been stopping. He was obliged at last to face the fact that his search had been in vain.

He had almost reached the hotel when he met a business acquaintance, who welcomed him warmly, for far and wide among legal men the firm of which Judge Blackwell was the senior member commanded respect.

"Well, well!" said the older man. "Is this you, Dunham? I thought you were booked for home two days ago. Suppose you come home to dinner with me. I've a matter I'd like to talk over with you before you leave. I shall count this a most fortunate meeting if you will."

Just because he caught at any straw to keep him longer in Chicago, Dunham accepted the invitation. Just as the cab door was flung open in front of the handsome house where he was to be a guest, two men passed slowly by, like shadows out of place, and there floated to his ears one sentence voiced in broadest Irish: "She goes by th' name of Mary, ye says? All roight, sorr. I'll keep a sharp lookout."

Tryon Dunham turned and caught a glimpse of silver changing hands. One man was slight and fashionably dressed, and the light that was cast from the neighboring window showed his face to be dark and handsome. The other was short and stout, and clad in a faded Prince Albert coat that bagged at shoulders and elbows. He wore rubbers over his shoes, and his footsteps sounded like those of a heavy dog. The two passed around the corner, and Dunham and his host entered the house.

They were presently seated at a well appointed table, where an elaborate dinner was served. The talk was of pleasant things that go to make up the world of refinement; but the mind of the guest was troubled, and constantly kept hearing that sentence, "She goes by the name of Mary."

Then, suddenly, he looked up and met her eyes!

She was standing just back of her mistress's chair, with quiet, watchful attitude, but her eyes had been unconsciously upon the guest, until he looked up and caught her glance.
